You'll have to do a little modification, but you can mount and use a standard rear rack to set up a delta trike for load4d touring.
- 2 shackle bolts
- 1 Avenir Rear Rack
- 2 grade 8 bolts to mount down struts to lower mount points / nuts and lock washers
Mount the shackle bolts on the middle crossbar, mount the down struts at the lower basket mounts on an EZ-3 trike (You will likely have to spread them a bit). Mount the forward rack mounts to the shackle bolts Bending is required).
It actually turned out looking like it was purpose built unless you look at the sloppy bends on the forward mounts
